Abstract: 1,130,082. Rectifying. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 1 June, 1967 [31 March, 1966], No. 14285/66. Heading H2F. A rectifier circuit is characterized in that a series resonant circuit L1, C1 is connected between the A.C. supply and the rectifier, this serving to reduce the ripple in the D.C. output and to improve the voltage/current relationship. In Fig. 3 there are three rectifier bridges D1- D3 arranged in cascade to provide three times the D.C. output voltage, A.C. being supplied to one bridge from the preceding bridge through two tuned circuits. With this arrangement the bridges D2 and D3 are supplied with almost a square wave, which is advantageous and the input A.C. may also be a square wave. A simpler circuit (Fig. 1, not shown) omits the bridges D2 and D3. A modified circuit (Fig. 6, not shown) has capacitors C2 and C3<SP>1</SP> moved to the other side of their associated inductances so that the paired inductances, L1, L2 and L2<SP>1</SP>, L3<SP>1</SP> may be housed together. In a three-phase system three columns of tuned circuits may be connected to a plurality of bridges arranged in cascade, the bridges being either three-phase (Fig. 4, not shown) or single-phase (Fig. 5, not shown). In the latter case if the secondary of the input transformer is star connected, earthing the star point increases the output voltage and decreases the ripple voltage. The inductances may be protected against excess currents by shunting them with a spark gap or a non-linear resistance, or by arranging that they saturate if the maximum rated current is exceeded.
